Outline of Final Research Achievements

Research of post embolization cerebral aneurysms using MRI depending various medical embolization devices was performed. We used Enterprize Stent and Neuroform Stent in these three years. Contrast enhancement of surrounding coil mass that appeared on recurrent aneurysms were statistically significant(p=0.043).But not so equivalent as initial angiographic result (p=0.002). We desired to evaluate post pipeline stent assist embolization by same MRI methods, but in these three year, this device did not introduced in our country. Although aneurysmal wall contrast enhancement that is same meaning as surrounding coil mass enhancement appeared statistically prominently in cases of recurrence, but variety of devices was limitted. So in near future after such various devices introduction, evaluation of many devices can contribute to establish the usefulness of our MRA methods adjusting to the variation of such new devices.
